Dual injection for torque reduction
A system comprises a torque control module, a combustion prediction module, and a fuel control module. The torque control module sets spark timing of an engine to produce a drive torque and determines an amount of delay to add to the spark timing to decrease the drive torque by a predetermined torqu...

| description | A system comprises a torque control module, a combustion prediction module, and a fuel control module. The torque control module sets spark timing of an engine to produce a drive torque and determines an amount of delay to add to the spark timing to decrease the drive torque by a predetermined torque. The combustion prediction module predicts whether a single injection of fuel will combust in a cylinder of the engine when the amount of delay is added to the spark timing. The fuel control module actuates a plurality of separate injections of fuel into the cylinder when the combustion prediction module predicts that the single injection of fuel will not combust. |
